To select a single node in the scene, choose on the Positioning panel and click the left mouse button on this node.
In this case, only the mesh surface you have clicked is selected. To select several mesh surfaces, holdShift and click required surfaces.

Notice

You can convert the selected node to a NodeReference by pressing Ctrl+Shift+G (or click Edit -> Convert to NodeReference).

To select several nodes, do either of the following:

Use the selection box: click and hold the left mouse button, drag the mouse to select the required nodes.
In this case, all surfaces of each mesh (if they exist) are selected.

Select using Selection Box

Selection can be performed in two modes: Window and Crossing. You can choose the mode via the drop-down list near the selection icon () on the Positioning panel:

Window Mode requires the whole object to be inside the selection box.

Crossing Mode makes the object selected if any part of it is inside the selection box.

Select one of the nodes, press and hold Shift to add nodes to the selection and Ctrl to remove.

Add and remove nodes from selection

Notice

To select all nodes in the world, press Ctrl+A.

When the node is selected, the following is shown:

Wireframe of the node

Bounding box of the node

Bounding box of the selected surface (or surfaces)

To remove nodes from the selection (deselect), press and hold Ctrl and click the left mouse button on the required nodes.

To deselect all selected nodes, press Ctrl+Shift+A.

The selected nodes can be positioned in the world by using one of the ways described below.

Notice

You can set a pivot point relative to which the selected nodes will be transformed.

Inverse selection can be useful for complex selections. For example, if you need to select all objects in a scene except the specific ones, you can select these specific objects and invert the selection.

On the Positioning panel, find and specify the required settings in the drop-down window:

Option

Description

Direction

Specifies the direction of dropping:

Up — find the closest surface above the object;

Down — find the closest surface below the object;

Up And Down — find the closest surface below the object and above it.

Offset from surface

Specifies the distance from the node's pivot point to the surface (in units).

Orient by normal

Specifies whether the node should be oriented by the surface normal.

Intersection mask

Sets an intersection mask that defines whether a node (or nodes) will be positioned on a surface to which it is dropped.
A node will be positioned on a surface if they both have matching intersection masks. Otherwise, the node will penetrate the surface.
